To all whom it may concern:

Be it known that 1, Aims WEINBACHER, a citizen of the United States,residing at Oshkosh, county of lVinnebago, and State of Wisconsin, haveinvented certain new and useful Improvements in Carpenters Knives, ofwhich the following is a specification. V

This invention relates to a combination cutting tool for use bycarpenters, cabinet makers and woodworkers generally and it has for anobject to provide a tool presenting a single cutting edge which can beused efficiently in a variety of ways and particularly as a chisel and adraw knife, not only when the latter are ordinarily used, but on, workwhen the use ofsuch instruments is desirable but the application of anordinary tool thereto impossible.

The invention has for a further object. to provide a tool of this naturecharacterized by cheapness, ease of keeping in condition, and lightnessin proportion to the work capable of being done.

For further comprehension of the inven-. tion, and of the objects andadvantages be had to the following specification and accompanyingdrawings, and to the appended claim in which the novel features of theinvention are more particularly set forth.

Figure 1 of the. drawings is a perspective view of a cutting toolconstructed according to my invention.

Fig. 2 is a rear edge view thereof.

7 Fig. 3 is a'transverse section on the line 3-3 of Fig. 2.

My improved tool comprises a relatively long shank cross section and ofoblong shape in cross section and inserted at one end in a handle 2 inthe usual manner, both the handle and the manner of securing the tooltherein being ordinary.

The outer end of the bar is provided with a triangular cutting head 3 inthe form of a lateral ofiset, this triangular head taon both sides fromthe point of meeting with the bar as at 4 and 5 to form a straightcutting edge 6 alongthe third side, the side 4 being a continuation ofthe outer edge of the bar 1. i

This third side is approximately double the length of 5 and they form attheir apex 7 a right angle, the cutting edge 6 extending in the medianline of the shank bar and at an acute angle thereto.

bar 1 of comparatively small As a consequence of this construction thetool presents in a single cutting edge a relatively fine portionadjacent the extreme point 8 of the tool which renders it pecul iarlyadapted for a drawing or pulling stroke to replace a drawknife andremove finely shaved portions of wood, while adjacent the point astouter cutting portion is formed which readily performs. the work of achisel, the combination being arranged to permit of use such as incorners or adjacent the meeting angles of a pair of vertically disposedsurfaces, where an ordinary chisel or draw knife cannot be employed. Forinstance, the tool may be employed as a draw anife and moved along thework in the eneral direction of the arrow A as in Fig. 1 permitting itto work close in to a vertical surface without interference of saidsurface with the proper handling of the operator, or it may be used as achisel and moved along the work in the general direction of the arrow Bin Fig. 1 likewise permitting free manipulation close to a verticalsurface.

The disposition of the cutting head also facilitates an oblique strokealong the work with a consequent increased ease of cutting permittingthe'use of a relatively ight tool on comparatively heavy work.

The tool may also be used in cleaning out grooves or like work thepointed ends facilitating work of this'kind.

Having thus described my invention and set forth the manner of its use,what i claim as new and desireto secure by Letters Patent, is

A. combination cutting tool for woorl-- workers comprising a shank barhaving triangular cutting head, one side of which is flush with one edgeof the bar. said head having a second relatively short side extending atan angle to the bar, and a third relatively long side extending at alesser angle to the bar than the said short side, said head taperingevenly in thickness from the point of'jnncture with the bar bothlongitudinally and transversely of the bar and forming a stralght-edgedcutting element presentmg an increasingly heavy cutting portionrearwardly from the extreme point of the tool.

In testimony whereof I have affixed my signature. I
